Many thanks to both David and Nick for helpful suggestions on this query about axis scales. Nita -----Original Message----- From: Nick Cox [mailto:n.j.cox@durham.ac.uk] Sent: 07 March 2005 14:26 To: statalist@hsphsun2.harvard.edu Subject: st: RE: RE: RE: yscale/range to plot Stata does not support scale breaks on axes, although they are occasionally asked for. You can easily cobble together something of your own by adding some extra ticks on either side of the axis, but that is up to you. On the broader question, there is discussion of this in the archives. There are at least two over-arching issues, or so it seems to me. 1. As far as the statistical arguments are concerned, the tacit presumption is that readers who can cope with a non-zero start to your axis graph should be able to look at the axis labels and work out what is being shown; and if you doubt this of your readers, you shouldn't do it! 2. As far as Stata is concerned, implementing scale breaks is a programmer's nightmare given the weight that _some_ users might then want to put on them. Suppose users wanted data points on either side of a scale break. What is then going to happen to lines supposed to traverse the whole graph? Or what happens when such a graph is -combine-d with another? Being able to say "But I wouldn't want to do that" doesn't rule out others' asking the equivalent, if only by accident. This is not, of course, an official view.
